Question

2) Numerical
Problems
a) A car at rest starts to travel in a straight path. It reaches a velocity of 12m/s in 4seconds. What is its acceleration? Assume that it accelerates uniformly.​(with explanation)​

Answer 1

Answer:

Explanation:

Acceleration= final- initial position/time taken

12is it's position

0 is initial position

Time taken=4sec

Acceleration=12 -0/4

=12/4

= 3m/s

Answer 2

Answer:

initial velocity = 0m/s

velocity = 12m/s

time = 4s

acceleration = v-u/t

acceleration = 0-12/4

                    = -12/4 = -3m/s2

its very simple first find the initial and final velocity then the time ( if time is not in seconds then convert and do further calculations ) . after this is the acceleration equation ( a= v-u/t ) with this equation find the acceleration ........

see its very simple and easy to score marks ....
